Graphcore, part of SoftBank Group, is a leading innovator in AI computing hardware, software, and data center infrastructure. This Staff Mechanical Engineer role provides technical leadership for the mechanical infrastructure supporting Graphcore's advanced machine learning and high-capacity computing environments.
You will own and maintain mechanical design standards, specifications, and owner requirements for data center projects. Key responsibilities include reviewing mechanical system builds, computations, blueprints, and technical requirements for quality and operational fit; translating AI and high-performance computing rack requirements into scalable cooling, airflow, hydronic, piping, and heat-rejection solutions; and providing technical direction to external consultants, developers, equipment suppliers, and engineering partners.
You will evaluate design options for reliability, maintainability, energy and water performance, capacity, and future expansion. You'll coordinate mechanical interfaces with electrical systems, building controls, fire protection, IT infrastructure, and site operations. Additional responsibilities include leading design reviews, resolving technical issues, documenting decisions and risks, supporting site inspections and factory acceptance tests, and verifying projects meet approved requirements, codes, and safety expectations before handover. You will also guide engineers, share technical knowledge, and assess emerging mechanical technologies for future deployments.
The role is Austin-based with approximately 10–20% travel for site visits, inspections, commissioning, and factory acceptance testing.
REQUIREMENTS:
- Bachelor's degree or equivalent experience in mechanical engineering or related discipline
- Experience crafting or reviewing mechanical systems for data centers, critically important facilities, or comparable infrastructure
- Knowledge of HVAC systems and equipment (chillers, pumps, air-handling equipment, ductwork, piping, hydronic systems, sequences of operation)
- Experience reviewing design calculations, drawings, specifications, equipment submittals, and control strategies
- Experience coordinating mechanical requirements with IT, infrastructure, facilities, and multidisciplinary engineering teams
- Experience supporting commissioning, inspections, acceptance testing, issue resolution, and operational handover
- Ability to provide clear technical direction and communicate decisions through concise documentation and collaborative reviews
PREFERRED QUALIFICATIONS:
- Experience with hyperscale data centers, colocation facilities, or Tier III/IV environments
- Professional Engineer license or comparable international credential
- Experience with high-density AI or high-performance computing infrastructure
- Knowledge of direct liquid cooling, high-capacity chilled-water systems, building automation, or advanced heat-rejection technologies
